•• In moderate and high risk ACS patients undergoing In moderate and high risk ACS patients undergoing an early invasive strategy, radial access was an early invasive strategy, radial access was associated with similar rates of ischemia and associated with similar rates of ischemia and significantly reduced protocol major bleeding significantly reduced protocol major bleeding compared with femoral accesscompared with femoral accesspp
